Jessica Alba Hair Transformation: The Star Goes Ombre (PHOTOS)

Posted: Updated:

Jessica Alba's been hard at work being a Hollywood mom and prepping for the follow-up to the 2005 cult hit "Sin City." The latest thing checked off her to-do list? Taking the ombre plunge.

To revive her stripper role in the upcoming "Sin City: A Dame To Kill For," Jessica had to go back to blonde. Lucky for us, the 31-year-old actress took to Twitter to document the annoyingly lengthy process of going ombre (believe us, we've been through it). "Bye bye brown hair," she tweeted along with a photo and video to say goodbye to her darker locks.

Later that day, Jessica tweeted several photos of the transition -- quite an educational series for those looking to go ombre themselves. Her stylist Rober Ramos of Estilo Salon in Los Angeles also maintains the coifs of Julianne Moore, Rachel McAdams and Eva Mendes, so Jessica was in good hands for the tricky procedure.

When it was all said and done, Jessica tweeted, "She got roots that Nancy." And she sure does. Even though the ombre trend is nothing new these days, we think the look suits Ms. Alba quite well. What do you think?
